Pi Day Party

As a teenager I remember geeking out in math class with my friends about the idea of “pi,” this never-ending number that is the ratio of the circumference of any circle to the diameter of that circle. It’s amazing how that number appears in so many math equations. When we found out that many people (mostly other math nerds like us) celebrated “pi” on its very own day, we knew had to join in the fun. The number “pi” is 3.14159… and so on forever so March 14th (3.14) turned out to be the day to celebrate. We proceeded to eat circular-shaped foods all.day.long. Yes, this is the kind of stuff that kids who take AP Calculus do and talk about for fun 🙂

Pi Day Party

I have been out of school for many years now and really haven’t used my knowledge of calculus all that much as a stay-at-home-mom. But my love of traditions, living life to the fullest and eating good food has kept “pi” day alive and well in our house. If you know me, I’m always up for some kind of celebration. I taught my kids early on about “pi” and they have been converted to the awesomeness of a “pi” party too. Instead of eating circular-shaped foods all day, we decided to make pie and share it with friends instead.

What we do: Invite over a bunch of friends on 3.14 (March 14th) and ask everyone to bring a favorite pie! Some years we’ve included dinner with “pizza-pie” or “chicken-pot-pie.” It’s really up to you. I’m all about keeping it simple so even though I may throw in a few appetizers, the focus is going to be on the pie. It’s the perfect time of year to be eating pie since we often haven’t thought about it for months since Thanksgiving and everyone is excited for a slice of something yummy.

Simple Gathering That’s Easy to Host

This is really one of the simplest gatherings you can have. Get your kids involved and make a pie together or pick one up from the grocery store. Don’t forget some plates, forks, napkins and cups from the dollar store and you are good to go. Even if you weren’t a math-lover in high school, pretty much everyone can enjoy a slice (or two) of pie.

And just to get your ideas going, here is one of my all-time favorite pie recipes from where I live in Kentucky. Derby Pie is a trademarked pie here in Kentucky and many places make and sell their own version during the spring around Derby time. We love this pie for pi day, Thanksgiving and we usually eat it again on Derby Day, or we enjoy making these Derby Day bars instead. I hope you try it and enjoy it warm or with a scoop of vanilla ice cream on top. Yum!
